Abstract
The utility model discloses an electric bicycle safety type chain stay sets up a safeties between chain stay and frame, safeties include with frame fixed connection's connected to the frame board, with chain stay fixed connection's chain stay connecting plate, be provided with the connecting hole on connected to the frame board and the chain stay connecting plate respectively, and one of them connecting hole is the arc hole, another connecting hole is the round hole, two are passed to the body of rod part of a fastener the connecting hole links together connected to the frame board and chain stay connecting plate, and can be relative motion through the body of rod part of fastener along arc hole motion between connected to the frame board and the chain stay connecting plate. When normally traveling, the utility model discloses do not influence the function of moving away to avoid possible earthquakes, if the junction breaking occur of chain stay and frame, this safeties play the insurance effect at once. Electric bicycle can ride slowly and smoothly carry out this moment, and can not be owing to the unexpected fracture of frame chain stay ear, electric bicycle rear wheel and frame separation for the personnel's tumble injury of riding.
Description
Technical field
The utility model relates to Electrical Bicycle field, relates in particular to a kind of Electrical Bicycle safety-type chain stay.
Background technology
Electrical Bicycle in use, due to jolting of road surface, so battery-driven car is designed to shock-absorbing, vehicle frame for shock-absorbing is completed by turning cylinder and Shock absorber, as shown in Figure 1, but such Electrical Bicycle, the junction 300 of chain stay 200 and vehicle frame 100 is concentrated due to stress, can rupture, fracture of frame occurs the personnel that ride in motion can be injured, can be in peril of one's life time serious.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of Electrical Bicycle safety-type chain stay, and rupturing with the junction solving chain stay and vehicle frame in prior art produces the problem of potential safety hazard.
To achieve these goals, the technical solution of the utility model is as follows:
Electrical Bicycle safety-type chain stay, it is characterized in that, one safety device is set between chain stay and vehicle frame, described safety device comprises the frame connecting plate be fixedly connected with vehicle frame, the chain stay connecting panel be fixedly connected with chain stay, described frame connecting plate is respectively arranged with on chain stay connecting panel the connecting bore being connected fastener, and one of them connecting bore is arcuate socket, another connecting bore is circular hole; Frame connecting plate and chain stay connecting panel link together through two described connecting bores by the shank portion of one fastener, and arcuately by the shank portion of fastener are moved and can do relative motion in hole between frame connecting plate and chain stay connecting panel.
In a preferred embodiment of the present utility model, frame connecting plate and Frame Welding.
In a preferred embodiment of the present utility model, chain stay connecting panel welds with chain stay.
In a preferred embodiment of the present utility model, the connecting bore on described frame connecting plate is arcuate socket.
In a preferred embodiment of the present utility model, the shank portion of described fastener is staircase structural model, comprise the enlarged diameter section that one section of reduced diameter section and one end coordinate with circular hole, described reduced diameter section is corresponding with arcuate socket, be arranged with outside reduced diameter section one so that fastener shank portion arcuately hole motion bearing.Further, wear-resisting steel bushing is provided with between described bearing and arcuate socket.Further, have fixing briquetting and packing ring in the arranged outside of arcuate socket, a clamp nut is connected to the outside of packing ring.
When normally travelling, owing to can do relative motion between frame connecting plate and chain stay connecting panel, the utility model does not affect incabloc function, if rupture in the junction of chain stay and vehicle frame, this safety device plays safety effect at once.Now, frame connecting plate and chain stay connecting panel still link together, but have loosening, and Electrical Bicycle can be ridden slowly and be carried out swimmingly, and can not due to the unexpected fracture of vehicle frame chain stay ear, and electrical salf-walking back wheels of vehicle is separated with vehicle frame, makes personnel's tumble injury of riding.
The utility model can reach the effect of security insurance.
It is simple that the utility model has structure, feature easy for installation.
The detailed description and obtaining that feature of the present utility model can consult the graphic and following better embodiment of this case is well understood to.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below in conjunction with specific embodiment.
See Fig. 2 and 3, a kind of Electrical Bicycle safety-type chain stay, arranges a safety device between chain stay and vehicle frame.Safety device comprises the frame connecting plate 1 being fixedly connected with (welding) with vehicle frame, the chain stay connecting panel 2 being fixedly connected with (welding) with chain stay, frame connecting plate is respectively arranged with on chain stay connecting panel the connecting bore being connected fastener, wherein, see Fig. 4-6, the connecting bore of frame connecting plate is arcuate socket 11, the connecting bore of the connecting bore of chain stay connecting panel to be circular hole 21(also can be chain stay connecting panel is arcuate socket, and the connecting bore of frame connecting plate is circular hole).
See Fig. 3 and 7, frame connecting plate and chain stay connecting panel link together through two described connecting bores by the shank portion of a fastener 3.The shank portion of fastener is staircase structural model, comprises the enlarged diameter section 32 that one section of reduced diameter section 31 and one end coordinate with circular hole.Reduced diameter section is corresponding with arcuate socket, be arranged with outside reduced diameter section one so that fastener shank portion arcuately hole motion bearing 4.Wear-resisting steel bushing 5 is provided with between bearing and arcuate socket.Fixing briquetting 6 and packing ring 7, clamp nut 8 is had to be connected to the outside of packing ring in the arranged outside of arcuate socket.
Arcuately by the shank portion of fastener move and can do relative motion in hole between frame connecting plate and chain stay connecting panel.When normally travelling, owing to can do relative motion between frame connecting plate and chain stay connecting panel, the utility model does not affect incabloc function, if rupture in the junction of chain stay and vehicle frame, this safety device plays safety effect at once.Now, frame connecting plate and chain stay connecting panel still link together, but have loosening, and Electrical Bicycle can be ridden slowly and be carried out swimmingly, and just there is the sensation of rocking left and right, and remind personnel's vehicle trouble of riding, please repair in time, ensure the life security of the personnel that ride.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification sheets; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
